CONDUCTOR CLAMP.

My invention relates to-conductor clamps l 13612 having' integrally united thereto, a'main and particularly to clampsfor holding', highvoltage, transmission-lineconductors.

' lOne object of my invention is to provide a device of the above-indicated'character that shall seat and clamp each of diverging or an-V gularly-related portions of a bent conductor.

Another object ofmy invention isto provide a conductor clamp that: shall comprise few Lparts and be easy to manipulate'.`

Another object of my invention is to pro,d vide a transmission-line clamp of .thedeadend type that shalletl'ectively secure both the line and depending-portions of the-'line conductor.

A further object of myinvention is to prol vide a clamp that shall be simple and durable in construction, economical to manufacture and effective in its operation;

' 1n transmission-l1ne practice, ldit, has been 1t is my aim to prevent such movement, to

reduce the number of parts and to' provide a clampthat is simple, strong, economicalland van improvement in other ways over clamps heretofore employed. i p

Accordingly, inpracticing my invention, I provide a Vclamp comprising ya main clamping portion and a mounting portion that are so integrally united anddisposed lin alignment, a diverging portion to which thevconductoris so secured, retaining lips that are so constructed and disposed' relative to the other parts and other features that are soV embodied in the structure as to attain they purposes set forth. y

Figure 1, of the accompanying drawing, is a side elevational view of a transmission-line or conductor clamp constructed in accordance with my invention,

Fig. 2 is a top plan view of in Fig. 1, and e e Fig. 3 is an enlarged view taken along the line III-III of Fig. 1.

The device comprises, in general, a memclaniping or lchannel portion 3, a mounting. portion 4, aportion 5 that diverges lfrom the portion 3, web portions 6 and 7, a pair of lips 8, a lip 9a clampl() on the web 7 and a main clamping member ormembers 12 on the portion 3. Y

The portions 8 and 4 are substantially .aligned with each other, except that the portion 3 is at the under side of a straight p01'- tion 14 of a conductor having a diverging or bent portion 15, and the portion 4, or at least, a terminal eye or elevis portion 16 thereof, 1s preferably centered relative tot-he axis of the conductor portion14, i i

The web: 'or reinforcing portion extends along the underl central portion of the chany e nels between the downwardly curved portion '5, adjacent to thelip 9, and a similarly downwardly curved portion 11 between the lips 8.

The lips 8, 'adjacent to one end of the channel 3, and the portions v4 and 9, adjacent to Atheother -end thereof, serve to rendery the channel deeper adjacent to the ends than at `its intermediate portion whereon the member f or members 12 are secured in position, by bolts 17 and nuts 18.

' 'lheclamp 10 preferably comprises an ordi-Y nary kU-bolt that is secured to the web 7, by

H'nuts 19I at the opposite side of the web. kThis arrangement of parts serves to prevent move- `1n`ent of the conductor portion 15 relative to f the seat portion 5. l 1 e e The portion4 is extended beyond the portion 5 4 to take the place of the usual separate connecting link employed in devices of this kindA and the web 7, which reinforces the portion 5, isshaped to provide proper clearance between the clamp and an insulator (not shown) to which tached. f e

By the structure described, a clamp is provided which comprises few parts, isA simple, compactl and durable in construction, iseasy to manipulate and has other qualities, such as economy of manufacture and effective oper ation.-

the portion 16 is to be atyWhile I have shown and described a parthe device shown ticular form of my invention, changes may be effected'therein without departing from the spirit and scope thereof, as indicated by the accompanying claims.

taining lip adjacent to the outer end of eachv of said portions and a mounting portion extending from one side only of said body member to a position in substantial alignment with one of said portions, and means on eaeh of said portions for Clamping a conductor.

3. A conductor Clamp Comprising a inember having a substantially straight elongated portion along a section of one side of which a conductor is to be clamped, a Conductor-retaining lip at one end of said portion, a clamp mounting portion at the other end of said portion, and a laterally-projeeting portion between said seetiou and said mounting portion for seating the conductor.

4. A conductor Clamp comprising a member having a substantially straight elongated portion along a section of one side of which a conductor is to be clamped, a conductor-retaining lip at one end of said portion, a clamp mounting portion at the other end of said poil tion, a laterally-projeeting portion between said section and said mounting portion for seating the conductor, and means for Clamping the conductor on said laterally-projecting portion.

5. A conductor elanip comprising a meniber having a substantially straight elongated portion along a section of one side of which a conductor is to be clamped, a conductora@- tween said section and said mounting portion for seating the conductor, and a retaining lip for the conductor on said late 'ally-pra jeeting portion.

6; A conductor clamp comprising a ineinbei having a substantially straight elongated portion along a section of one side of which a conductor is to beelamped, a conductor-retaining lip at oneend of said portion, a clamp mounting portion at the other end of said poi'- tion, a laterally-projecting portion between said section and said mounting portion for seating the conductor, a retaining lip for the conductor on said laterally-projeetingV portion, and means for clamping the oonduetor on said laterally-projeetingportion.

7. A conductor elamp comprising a meniber having a straight eonduetor-reeeiviiig portion for positioning under the conductor,

a pair of retaining lips atene end of said portion at opposite sides of ther eonvduetor, an integral mounting portion in substantial alignment with said lportion at the other end thereof, a widely Curved conductor-seat portion diverging` laterally from said first portion intermediate the same and the outer end of said. mounting portion, a retaining. lip on said diverging portion, a web portion oxtend- `portion for positioning'under a conductor,

longitudinally-spaced portions curving down- Vwardly from said portion,'and a reinforcing web extending along the under side of the channel portion between said curved portions.

9.' A Conductor clamp Comprising a Channel portion, apairof retaining lips adj aeent to one end thereof, a single retaining lip adj aeent to the other end of theeliannel at oneV side thereof and means adj aeent to said single lip at the opposite side mounting'` the Clamp.

In testimony whereof, I have hereunto 'subscribed my name this 8th day of April,'l927`.
